Abstract
Provided are a toner and its production, a developer, an image forming method and an image forming apparatus. The toner has excellent fixation characteristics of good releasability, hot offset resistance, folding resistance, surface glossiness, and OHP transparency. The toner contains a binder resin, a colorant, a release agent and an inorganic particles. The inorganic particles therein contain inorganic particles (A) having the mean primary particle size not less than approximately 5 nm and less than approximately 30 nm and inorganic particles (B) having the mean primary particle size not less than approximately 30 nm and less than approximately 200 nm.
